An exemplary LED package includes first and second electrodes, an LED chip and two electrically conductive wires. They include a source of welding-type power and at least one welding system peripheral. A cutting-engaged angle \u03b1en is determined from a radius R of a tool and a depth of cut I into a workpiece. The device is placed on a wearer by using placement lobes associated with the flange. The power module, which may be mounted in a convenient location, preferably on the towed vehicle, receives the braking information from the control module and secures power from the towed vehicle to engage its brakes.
